The team is requesting the delay while it goes along with an independent investigation into the circumstances that led to Incognito's indefinite suspension on Nov. 3. Incognito's hearing is currently set for Thursday.

The Dolphins suspended Incognito for conduct detrimental to the team following reports that he used explicit language and racial slurs in voicemails to teammate Jonathan Martin. Incognito's grievance argues this violates the collective bargaining agreement.

Incognito filed a non-football injury grievance against the team last week. According to Mortensen, his complaint charges that the Dolphins have not yet identified specific examples of the detrimental conduct.

In an interview with Fox Sports' Jay Glazer a week ago, Incognito downplayed the actions that led to his suspension as part of the Dolphins' locker-room culture.

“This isn’t an issue about bullying,” Incognito said. “This is an issue of my and John’s relationship. You can ask anybody in the Miami Dolphins locker room, ‘Who had John Martin’s back the absolute most?’ and they’ll undoubtedly tell you [that it was] me. All this stuff coming out … it speaks to the culture of our locker room. It speaks to the culture of our closeness. It speaks to the culture of our brotherhood. The racism, the bad words … that’s what I regret most, but that is a product of the environment, and that’s something we use all the time.”
